In addition to the equipment we routinely manufacture and provide to the scientific community and industry (listed below), we also offer custom lab and field equipment design and manfacturing services
Lignin Analysis Equipment
​Our lignin analysis system, the "Cupric Oxide method," has been the academic and industry standard for over 40 years
The method provides extensive details on plant organic matter source and preservation in soils and sediments

Lignin is a complex molecule produced in large quantities by land plants.  When plants decay lignin is introduced into soils, and rivers carry large quantities of lignin into lakes and the ocean.  The analysis of lignin in the waters and sediments of aquatic systems can provide important clues into earth's carbon cycle and environmental change.
​
​A full set-up consists of:
  • Reaction vessel oven (modified HP5890 GC) to perform the thermochemical oxidation on 12 samples simultaneously
​
  • We can provide the full oven set-up, or can modify an oven door you send us
  • 24 monel steel reaction vessels. Precision manufacturing, airtight, corrosion resistant
​
  • We also provide tool sets for sealing/opening the vessels, as well as the ball bearings and o-rings for proper use
Sampling Equipment
We manufacture rugged, cost effective shallow water sediment coring devices that are ideal for sampling sediments in wetlands, estuaries, and lakes.  Coring tubes are hand-beveled acrylic or clear PVC and can be ordered separately.​
We also offer aquatic foam sampling equipment, personally designed and tested by technicians at GAR
Have a custom need for aquatic sampling equipment and don't know where to find it?
